Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“I'm making this on my own. The whole journey from Waterloo to Haven is already playable: the opening at Waterloo, routing across the network, crew, scavenging, infection, Mara's side quests, the story, and the ending.

What I can't do on my own is play it enough. The systems all lean on each other. A small change to fuel use shifts which routes make sense, and a change to how many people board shifts food, seats, crew and morale for the rest of the run. Early Access gets me a lot more complete journeys than I can manage myself, and that's what I need to balance it properly, explain the bits that aren't clear, and find the parts of the route that are thin.

During Early Access I'll also be adding more station stories, passenger and survivor encounters, side quests, event chains, accessibility options, and quality-of-life improvements.”

Approximately how long will this game be in Early Access?

“About 12 months. That's an estimate, not a date. It leaves Early Access when the campaign content, balance, accessibility, performance and platform support are where they need to be.”

How is the full version planned to differ from the Early Access version?

“More station stories and branching event chains along the whole route, more passenger and survivor arcs, and more consequences that carry forward. Balancing of routing, scavenging, infection, resources, morale and reputation based on what people's runs actually look like.

Better onboarding, more accessibility options, and controller and Steam Deck support that's been tested properly rather than just wired up. Steam Achievements and Steam Cloud are in the build and being validated.

Priorities will move depending on what the feedback says needs the most work.”

What is the current state of the Early Access version?

“The full single-player campaign from Waterloo to Haven works, beginning to end. You can set up the opening train, accept or refuse named passengers, hire crew, pick routes across the real network, scavenge with named crew, meet survivors, take on Mara's side quests, pay or refuse tolls, repair, treat the sick, react to infection spreading, and make choices that follow you to the end. Runs save locally and can be continued.

It's not content-complete or fully balanced yet. The big stations have more bespoke story than the small ones. Onboarding, accessibility, controller support, performance and Steam integration will all keep improving during Early Access.”

Will the game be priced differently during and after Early Access?

“The price might go up when it leaves Early Access if the game has grown a lot by then. Any change will be announced in advance.”

How are you planning on involving the Community in your development process?

“Steam Discussions and the Discord server are where to report bugs and tell me how a run went. I'll post updates on what's changing and what I'm working on.

Reports from complete runs are the most useful thing, because a decision at Waterloo can bite you at Carlisle. I'll read everything, but I'm not promising every suggestion goes in. It has to fit the game.”

About This Game

Britain collapsed about a year ago. The infection burned through London long before you got here, and what's left at Waterloo is a dark station with one loaded train in it. You're in charge of that train. It's called Mercyrail, it was paid for by a man who helped break the railway in the first place, and it's heading north to a rumoured survival colony called Haven. Nobody on board has seen it. It's a name passed along the wire, and the only place left that anyone still talks about as if it's there.

Everyone still alive at Waterloo is already on board. From here on the country is empty. Stations are dark, the broadcasts are on loops that outlived whoever recorded them, and the only new faces come from what your crew finds when they go looking. This isn't a commuter train... it's the last public service anyone has, and how you run it is up to you.

Run It All From One Terminal

You run the whole train from a CRT terminal: pick the route, read the dossiers, send the crew out and wait for their reports, all through one old screen that was only ever built to run a timetable.

Real UK Rail Network

Every station and every line comes from OpenStreetMap, about 2,600 stations and 2,800 connections, and you can go anywhere on it. The map reveals itself as you go. There's no set route north and you can take any route you like as long as you can keep the train moving. Lines get blocked by failed points, flooding, barricades and derailed stock. Clear them with fuel and spare parts, or take the slow way round.

Decide Who Gets a Place

Every seat is another mouth to feed and water the whole way north, and the more you take the faster the hold empties, so what leaves London is your call: a first class train for a few, a steerage train for everyone else, or a mix that has to live with itself for the rest of the journey. The people you turn away are remembered.

From there, every new arrival comes from what your search parties find: a survivor worth a seat, or an abandoned carriage worth dragging home. Whichever way you build it, that's the community you're responsible for getting to Haven alive.

Keep the Train Running

Keep food, fuel, medicine, water and spare parts coming into one shared hold by scavenging at stations. Repair the train at depots. Treat the sick. Every abandoned carriage you couple on changes what the train burns to move, and every survivor you bring aboard is another mouth to feed.

Send the Crew Out

Need more resources? Send a crew out to search the area. Reports come back in real time and you decide whether to push deeper for a bigger haul or bring them home before someone gets hurt. Go too far and people come back wounded, infected, or not at all. Sometimes they find survivors who need a seat, or an abandoned carriage worth coupling on. Crew get better the more they go out, which makes losing one hurt more.

Every Choice Matters

The story runs the whole length of the line, several arcs deep, and every choice you make in it matters. Who you help, who you turn away, what you pay and what you refuse. None of it is forgotten. The train that reaches Haven is the one you made.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Yes, this game has been built with AI.

As a software engineer for over 15 years, I wanted to see how far I could push AI to bring my idea to life. I built the initial prototype myself, but have used AI extensively to turn the prototype into a fully functional game that looks and feels the way I imagined. This is still months of work with over 50 hours of playtesting to bring it to life.

AI has come a long way, and game development is evolving fast. This game would never have left the prototype stage without it. Please consider giving it a chance.
